Abstract
The invention relates to a method for manufacturing mating sintered parts obtained from breaking a unitary preform. It is characterised in that: a) a preform is pressed from metal powders, making a superficial groove (3) in this preform, the groove being situated in a plane with a view to subsequent breakage, b) this preform is pre-sintered with a view to mechanically consolidating it, this preform nevertheless remaining fragile, c) it is made denser, possibly by recompression, d) housings for the components for mechanically joining the final parts together are possibly machined in this preform, e) this preform is broken into at least two parts, f) final sintering is carried out, g) the parts are cooled. The invention is particularly applicable to the manufacture of connecting rods and connecting rod caps or of undercut or not undercut annular components (split in the axial plane).
